depends on the other parts and what you want . a 1/4 engine has diffrent requirements than a daily driver especially with the turbo.

Flow rates are a little bit different with the turbo you shouldnt be looking at max flow but yor mid depending on your cam and lift and duration.

I've found that depending on cam and boost levels max flow N/A get destroyed anyhow. the presurre more than makes up for the porting for a n/a application. also you want velocity on the exhaust side.

I'm looking at AFR 205 for my Race motor . solid lifters and those heads should put me past 750 hp . it dynod at 712 in present form and the dyno graph indicates the lifters were holding the upper hp down torque was huge i need to get a scanner to post for others to offer suggestions.
